Wetland/Estuary Structure and Functions

Young scholars explore and experiment with the concept do new kinds of insects appear after soil modification. They assess and review scientific methods of observation, predicting, variables, math skills, ratio, proportions, graphs and...

Students study the basics of soil science. They research and gather data through readings, videos, and performance of laboratory investigations. As a team they generate oral and written recommendations for the amendment of soil.

Pupils grow grass or radish seeds in this experiment, which takes three to four weeks to complete. They become familiar with basic soil analysis techniques, as well as, explore the importance of analyzing soil samples.

Fertility in soil is the topic of this presentation. Future farmers will be able to define fertilizer, list ten essential soil elements, and describe the roles of both primary and secondary nutrients in plant production. Although there...

Soil is 25 percent air on average. Learners may have a difficult time accepting that fact without a visual to demonstrate the property. A quick video lesson uses a model to show how this percentage is true and also discusses the...

Fertilizer can mean the difference between a profit and a loss. Scholars use an online interactive to explore the effects of fertilizing in agriculture. Given information about the nitrogen levels in the soil, they decide the fertilizer...

Students lay out transect lines beside a local stream or river. There they record species of plants and insects living around the stream. By doing so, students explore how to use transect sampling techniques, use a variety of methods to...

Nitrogen is an essential element for productive farming. An interactive lesson explores the chemical makeup of different fertilizers and their corresponding nitrogen content. The interactive challenges individuals to complete molecular...

Teach your class the descriptive characteristics of soil. Provide information about particle size and a flow chart for assessing texture. Soil scientists then analyze samples and hypothesize which would be the best type for a rain...

Breathe some new life into charcoal. Scholars use biochar to improve soil fertility. They test the effectiveness of this addition by conducting an experiment with soil having 0%, 2%, and 4% biochar.
